FRANCIS M. UI-ILER, OF LINCOLN, NEBRASKA.

PENCIL-SHARPENER.

SPECIFICATION forming part of Letters Patent No. 467,446, dated January19, 1892. Application filed February 20, 1891. Serial No. 382,217. (Nomodel.)

To all whom it may concern:

Be it known that I, FRANCIS M. UHLER, a

citizen of the United States, residing at Lincoln, in the county ofLancaster and State of Nebraska, have invented a new and usefulPencil-Sharpener of which the following is a specification. Thisinvention is an improvement in pencil sharpeners and holders, and has,among other objects, the special object of protecting the pencil-pointfrom injury during sharpening and when not in use.

\Vith this object in View the inventionresides in the various noveldetails of construction and in the combination of parts hereinafterfully described, and particularly pointed out in the claim.

In the drawings in which I have illustrated my invention, and in whichlike figures of reference indicate corresponding parts, Figure 1 is aside elevation of my device.- Fig. 2 isa longitudinal sectiohal view ofthe same, and Fig. 3 is a cross-section on the line w w of Fig. 1.

In the drawings, 1 designates a tubular holder, which is provided withthe usual slit to enable it with ease to receive the ordinary pencil.Upon one end of the holder a raised roughened collar 2 is provided toenable the user to obtain a firm grasp of the device. Beyond'this thereis the conical cutter portion 3, provided with the slot 4 and thecuttingedge 5, the said cutting-edge being slightly inclined tocorrespond with the desired shape of the pencil at the point.

6 designates a small tubular projection which extends from the smallerportion of the conical cutter 3. This small tube 6 is provided for thepurpose of protecting the pencil-point as it is sharpened and graduallythrust forward. The chief advantage of this invent-ion is to be found inthis tubular pro iection 6.

7 indicates an ordinary pencil.

In operation my improved pencil holder and sharpener is very simple andeffective. The pencil has one of its ends inserted in the tubular holder1 and thrust forward sufficiently far to bring the said end in contactwith the cutting-edge 5, situated in the conical cutter portion 3. Theuser holds the device between his fingers by the collar 2 and rotateseither the pencil within the holder or the holder around the pencil, orhe rotates both pencil and holder in opposite directions. The knife bythis operation is brought successively and gradually in contact with thewooden casing of the pencil and shaves the same to the required shape.

This invention has for its object to and does protect thepencil-pointduringthe sharpening and after it. The tubular projection 6provides a guard for the pencil-point while it is sharpening and alsoafter it has been sharpened, and in order the more effectually to dothis the said tubular projection is placed in alignment with thelongitudinal axis of the holder-that is, in the longitudinal axis of thepencil to be sharpened.

The tubular holder 1, it will be observed, is open at each end and istherefore adapted to receive and be permanently located upon the pencil,or, in other words, serves as a holder for the pencil. When the pencilre quires to be sharpened, the holder is simply rotated so as to removethe surplus wood and permit the point to pass sufficiently far throughthe reduced portion 6 to be used. When not in use, the pencil maybeslightly withdrawn in the tube 1 and the lead protected.

Having thus fully described my invention, What I claim as new, anddesire to secure by Letters Patent, is-

The herein-described pencil-holder, pointprotector, and sharpenercombined, the same consisting of a tubular holder open at each end, oneend terminating in a conical cutter portion provided with a cutter and areduced tubular projection 6, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixcdmy signature in presence of two witnesses.

M. A. BLANCHARD.
